Wilwood's new Combination Proportioning Valve substantially simplifies mounting, plumbing, wiring and brake proportioning adjustments on vehicles with custom brake systems. With an integral brake light switch, it can be used in VW applications which require relocation of the brake lamp switch. With a 0-57% reduction range, it outperforms the factory VW proportioning valve in terms of adjustability and dynamic operation.
The combination block maintains full isolation between front and rear fluid circuits and can be used in conjunction with any tandem outlet or dual mount master cylinder assemblies. The rear circuit has a single inlet and single outlet with the adjustable proportioning valve. The front circuit has a single inlet with two outlets. It can be run as a single outlet with one outlet plugged, or used to split the plumbing on its way to the front calipers.
**Note, 3/8-24 thread outlet fittings can be used in conjunction with factory VW brake hardline, or 3/16" generic hardline. M10 fittings can also be used on 3/16" hardline, but a 3/16" flare must be used**
